TIMING DEVICE FOR EGG-BOILERS.

Specification of Letters Patent. Patgnted lllay'12,1914g,

Application filed April 5, 1913'. SerialNo. 758,993.

To all whom it may conoerrilflf 7 Be it known that I, CHARLES CALVERT LAMB, a citizen of the United States, and a resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in- Timing Devices for Egg-Boilers; and I do herebydeclare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to a timing device for e boilers and the'like.

" provide tt1I111I1g-ClGV1C6 which is not only simple and inexpensive in construction, but

Among the objects of the invention are to is reliable in its operation and will eifect the prompt withdrawal of the egg-holding receptacleand its contents from the water in the boiler whenthe time required for cooking the eggs has expired. 7

' A further ob'ect of the invention is to provide means for retarding or checki'ngthe speed of the operative parts which lift the egg-holding receptacle from the water in the boiler, so that said receptacle will not be too rapidly moved and suddenly arrested when so lifted out of the water.

The invention consists in the matters here inafter described and more particularly pointedfout in the appended claims.

In the accompanying drawings, illustrating my iiiventioii Figure 1 is a vertical sec tioiial view of a timing device for egg boilers constructed in accordance with my invention; the egg-holding receptacle and the other parts being shown in one position;

Fig. 2 is a vertical sectional view of the tiniing device, the egg-holding receptacle and the other parts being shown in a different 'positionthan that illustrated in Fig. ,1; Fig. 2-, is a top view of the timing device shown in l igs. 1 and 2, certain parts being omitted for the sake of clearness of illustration; Figs. 4t and 5 are fragmentary vertical sectional views taken on planes indicated-by lines i4" undo-5 of Fig. 10,'respectively; both views being made ona smaller scale than that used in Fig. '10; Fig. 6 is afragmentary View in side elevation of a portion of the casing pro-' vided with the vertical slot, showing a stop member on said casing; Fig. 7 is a ragmen tary, cross-sectional view taken on line 7-7 of Fig. 6; Fig. Sis a vertical sectional view through the lower end of the casing and the auxiliary water tank; the other parts of the device being omitted; Fig. 9 is a cross-sectional view taken on a plane indicated by line 9 9 of Fig. 8'; Fig. 10 is an enlarged, cross-sectional view, taken on a plane indicated byline lO-lOof Fig. 1; the auxiliary or timing weight carrying sleeve being shown in engagement with the spring-controlled guide. member; Fig. 11 is an enlarged V16W'1I1 side elevation of certain details of construction to be hereinafter described; Figs. 12 and '13 are side and front views in elevation, respectively, of the escapement mechanism to be hereinafter described.

Referring to the drawings, illustrating one form of my invention, the same consists of a'tube or tubular casing 20placed in an upright position within, and at one side ofan egg boiler or tank 21. The lowerend of said casingQO is seated on the bottom wall of said tank 21, and is closed by a bottom wall 22, so that water in said'taiik 21 surrounding the lower'end of said casing, will not enter the same. Located at the top of said casing andmountedon' a horizontally Y arranged shaft. the ends of which are'journaled in the side walls of the casing is a sheave or grooved pulley 23, over which is trained a flexible member 24, preferably having the form of a metallic tape. One end of said flexible member 24. extends outside of said casing 20, while the other end of the same is within said casing. Secured to the end of said flexible member 24 withoutsa-id casing 20- is a rod 25 to the lower end of which is attached or secured a wire -mesh basket or foraminous receptacle 26 to be submerged in and raised out of the water in said tank 21. Said basket or receptacle 26 is adaptedto contain the eggs or other articles to be cooked by the heated water in said tank 21. .tigidly secured to the outer surface of the casing 20. adjacent to the tank 21, is a guide bracket 27, through which saidrod 25 passes. Adjacent the upper end of said'rod 25 is secured a handle '28, adapted to be grasped for lowering the basket 26 into said tank 21. Secured to the end of said-flexible member 24 within said casing 20 is a rod 29. to theloweiend of which isattacl ed a weight 30. Said weight 30' is somewhat less in weight than said basket or receptacle 2% nd its contents. As shown in the drawings. said weight 30 is adapted to slide vertically within said casing 20, in the raising and lowering of said basket The basket carrying rod 25, the

flexible member24 and the weight-carrying rod 29, are of such length with respect to each other, that said weight 30 is adapted to move in said casing a distance equal to the" distance said basket 26 is moved when lowered into and lifted'from said tank 21. Mounted to slide endwiseon said weightcarrying rod 29 is an elongated sleeve 31,

to the lower end of which is attached a secondary weight 32 adapted to slide vertically in the casingabove the weight 30. Said weight32 is of such gravity that, when it rests upon and acts in connection with the counterbalance weight 30, above referred to,

the gravity of the two weights will be sufli- I the full length of said sleeve 31. Said sleeve is substantially less in length than half the length of said rod 29. Projecting outwardly from one sideof said auxiliary weight'32, and through a vertically arranged slot 34 in the wall of said tubular casing 20 is a handle 35, by means of which said auxiliary weight 32 and the sleeve 31 connected therewith may be raised .(see Figs. 3 and. 5).

Extending into the casing 20 through the side wall thereof, at a point above its center and to 1 one side of the counterbalance weight-carrying rod 29, is a horizontally arranged shaft 36, upon the inner end of which, within said casing, is mounted and rigidly secured a rack-pinion 37, the teeth ofwhich, on'its side adjacent to the sleeve 31, are directed upwardly and correspond with, and are adapted tobe engaged by, the teeth 33 on said sleeve 31, when the latter is raised by the handle 35 into position for engagement of its teeth 33 with the teeth of said rack-pinion 37. (See Figs. 4 and 5.) Mounted upon and rigidly secured to the outer end of said shaft'36, namely, that end outside of the casing 20, is a gear wheel38, greater in diameter than the rack-pinion 37. Said gear wheel 38 is located within a box 39 secured to the side of the tubular casing 20, and which contains the operative parts of an escapement mechanism to be hereinafter described. Said shaft 36 is journaled in the wall 39 of said box 39 adjacent and secured to the casing 20, in any suitable man ner, but preferably by machine screws 39,

only one being shown in the drawings, (see Fig. 10). Surrounding said shaft 36' and extending between said box wall 39 and the rack-pinion 37 is a spacing sleeve 40, which prevents said pinion 37 from moving endadapted to slide'in a guide aperture provided therefor inthe side wall of said casing 20. Secured to and in alinement with said squared end 43 of said guide member, and located outside of saidcasingis a push rod. 44 provided at its outer end with a head 45, between which and the wall of said casing 20 is located a spring 46, which acts on the push-rod to throw the same outwardly. As shown in the drawings, said spring 46 is of coiled form and surrounds said push rod 44. Located within said casing 20 andextending from the'inner wall thereof toward the yoke 42 of said guide member 41, and in alinement with the squared end 43 of said guide-member, is a guide rod 47 the inner end ofwhich extends into and has sliding engagement with a recess 48 provided in a lug 49 on the yoke 42" of said guide member 41, (see Figs. 10 and-11). Through the combination of the guide rod 47 and the squared end 43, said guide member 41 is supported in' proper position within thecasing 20 and permitted to have endwise movement therein. At the inner end of said squared part 43 of said guide member 41, and within said casing 20, said guide member is provided with a stop flange 50, adapted to contact withtheinner surface of said casing, and

limit the endwise movement of said guide member 41. When the stop flange50 of said guide member 41-is in contact with the inner surface of said casing 20. (see Fig.4 2), the counterbalance weight-carrying rod 29 passes freely through the yoke 42. Said yoke 42 is, however, in t'he path of movement of the auxiliary weight-carrying sleeve 31, and is moved endwise against the tension,

of said spring 461:0 accommodate said sleeve 31 when the said sleeve is raised and enters within said yoke 42. When said sleeve 31 is within said yoke 42, the tension of said spring'46 acts to hold said sleeve 31 in contact with the pinion 37, so that the teeth of the sleeve will be held in engagement with the teeth of the pinion. By reason of the fact that the rack teeth 33 on said sleeve 31 .are directed downwardly and the adjacent 'teeth' of said pinion 37 are directed upwardly, said rack teeth 33 on the sleeve 31 will pass by the teeth of the pinion 37 in the'upward movement of the former without effecting the rotation of said pinion. In the downward movement of said sleeve 31, the rack teeth 33 thereof, engaging the teeth of said pinion 37, will etfect the rotation of said pinion. The upper end of said sleeve 31 is beveled or rounded so thatthe same will readily enter within said yoke 42 in the upward movement of said sleeve.

The escapement'mechanism referred to, as-

shown in the drawings, is constructed as fol lows: Mounted on and rigidly secured to a horizontally arranged shaft 51 extending between and journaled in laterally spaced brackets 52', 53, which'are located within and securedto the wall 39 of the box 39,is a pinion 54, withwhich meshes the geanwheel 38, hereinbefore referred to.- Mounted on the end of said shaft 51 is an escapement wheel 54, provided with laterally extending ries at its upper end a pair of horizontally arranged, oppositely extending arms 58, 59, upon the outer ends ofwhich are secured weights 60, 6-1. Said vertical shaft 57 is rocked by the action of pallets 56, 56, one of I which is located above and the other below the shaft 51; the weights 60, 61 acting to retard the oscillatory movement of. the shaft 57, as common in such escapement devices.

Located within said tank 21 and placed in an upright position beside and in contact with said casing 20 is'an auxiliary tank 62 adapted to contain water. '(See Figs. 8 and 9.) Said casing'20 and said auxiliary tank 62 are in communication with each other through an aperture 63 opening through the contiguous walls of said casing and tank, at their lower ends (see Figs. 8 and 9). The water-in said tank 62-flows into the lower end of said casing 20 as'thecounterbalance weight 30 is raised. When the weight 30 moves downward, or toward the lower end of said casing 20,'the .water standing in the lower end of said casing is forced through said aperture or passage 63 into said tank 62, and acts to retard or check the speed of said weight in its descent.

For convenience in setting the auxiliary or t-imi'ng weight 32, 'so that the sleeve 31 may extend a distance above the pinion 37 to retain the basket or receptacle 26 in the water in thetank 21 a desired length of time, I have provided a vertically'adjustable stop-member 64: uponthe casing 20. Such stop-member, as shown in the drawings,

comprises aclampscrew 645 having a screwthreaded stem which extends through the vertical slot 34; in the casing 20 and outer and inner clamp plates 65 and 66 adapted to beclamped against the outer and inner surfaces'of said casing by the action of said clamp. screw 64; turns freely in the outer ath of movement of said auxiliary or timlng weight 32 when the same is lifted, Said clamp screw 6% turns freely in the outer plate 65 and its stem has screw-threaded engagement with the inner plate 66. Said outer plate 65 is provided with a finger or pointer' 65f adapted to be moved vertically over the graduations-orvmarks of a scale on the outer surface of said casing. adjacent said slot 34: (see Rigs. 6 and 7). By moving said stop member 64 vertically in said slot 34: the finger '65 may be'set at the mark or of timerthe .egg holding receptacle or basket 26 is to remain in the water in the tank '21. h

- The device hereinbefore described. and shown in the drawings, operates as follows:

v When the several parts of the device occupy the positions shown in Fig. '2, the basket or graduation ofa scale determining the length receptacle 26 is raised out of the water in the boiler or tank 21 the rack teeth 33 being then out of engagement with the pinion 37 and the auxiliary weight 32 resting on the counterbalance weight 30. The gravity of the combined weights maintains the basket 26 injits raised position both before and after the eggs or other articles to be cooked or boiler are placed in said basket or receptacle 26. The stop member 64- having been previously set with its pointer 65 at the mark or graduation on the scale determining the length of time the eggs are to remain in the boiling water, the auxiliary weight 32is raised from contact with the counterbalance weight 30 by the handle 35 until stoppedby contact with the. said. stopmember As the weight 32is liftedthe upper end of the sleeve 31, to which sa d weight is connected, passesthrough said guide member L1 and stands above the pinion 37 with theteeth of the latter engaged by the rack-teeth 33 on said sleeve 31. The auxiliary weight .32 will then be supported by the engagement of the teeth on the sleeve 31 with those of the pinion, at a point above the position occupied by the main weight 30, when the latter is'lifted to the extreme limit of its upward-movement and the basket 26 depressed to the bottom of the tank. Following the lifting and setting of the auxiliary weight 32, the basket 26 is then lowered into the boiling water in the boiler or tank '21, by the application of sufficient force for this purpose to the handle 28 at the upper end of the basket carry- .ing rod 25. The depression of the basket 26 acts to pull downwardly on the outer end of the flexible member or. metal tape 24, running over the pulley 23, 'and to raise the rod 29 and counterbalance weight 30 attached thereto. As the counterbalance weight 30 is raised the water in the auxiliary tank 62 flows into the lowenend of the casing 20 through the port 63 and occupies the space vacated by the ascending weight 30. When the basket 26 is fully depressed, the counterbalance weight 30 stands at adi stancebelow the auxiliary weight 32 which will be greater or less according to the vertical poj-when lifted, or upon the distance to which theupper end of the sleeve 31 has been car ried above the pinion 37 in lifting the auxiliary weight for setting the same.- W'hen the main and auxiliary weights are both in their raised positions, as shown in Fig. 1 of the drawings, the level of the water in the lower end of'the casing 20 will be below-the bottom of said main weight 30. Said main weight 30, being somewhat lighter in weight than the basket 26, has no lifting effect upon said basket, and consequently both basket and weight remain in the positions shown in Fig. 1, during the descent of theauxiliary weight into contact with the main weight. As soon asthe auxiliary weight is released, after being lifted to the desired extent, or to the point indicated by the adjustable stop, as described, said' auxiliary weight 32 begins to descend and the rack teeth 33, engaged with .the pinion'37, operate to rotate the same in the downward movement of the sleeve 31. The speed of rotation of the pinion 37 being controlled by the escapement mechanism, the auxiliary weight will descend slowly and will occupy a period of time in its descent, before coming into con-' tact with the main weight 80, depending on the length of the upper part of the sleeve that was carried above the pinion in setting the auxiliary weight for acting. The mainweight 30 will usually be lifted and the basket lowered, after the auxiliary weight has been lifted or set'for action, but such' lifting of the main weight will be accomplished immediately after the lifting of the auxillary weight and before the same has descended any'considerable distance, owing to the slow downward movement of theauxiliary weight. The sleeve 81 and its attached weight will continue their downward movement, occupying such length of time in so doing as determinedupon for the;

cooking'of the eggs, until the rack teeth 83 on said sleeve 31 become disengaged from the pinion 37, when the auxiliary weight will drop into contact with and rest upon the main weight 30. The sleeve 31 and the weight 32 carriedthereby, at this time will be in the position shown in Fig. 1; the auxiliary weight 32 resting upon the counterbalance weight30, and both weights being in movement toward the bottom of said casing 20. The gravity of the two weights $0 and 32 is sufliclent to overcome the weight of the basket 26 and its contents, so as to raise the basket out of the water in the boiler or tank 21. As the weights 30 and 32 move toward the bottom of the casing 20, the

weight 30 comes into-contact with and displaces the water in the lower end of said lower end, of the casing, and the basket 26 is drawn slowly or gradually out of the water in the tank 21. Anysudden upward movement of said basket 26, such as might act to throw the eggs outof the same, is

thereby prevented. As a further improvement,I attach to the bottom of the counterbalance weight 30 a float 30, which may be made of cork or the like. A float thus applied renders the weight-somewhat buoyant, .and this further retards the movement of said weights 30 and 32, after the former enters the water in the lower end of. said casing 20. v

The provision of the port in the lower end of the casing, with means for furnishing a supply of water to said casing, constitutes in effect a controlling lneans for retarding the speed of the counterbalancing weights in the latter part of their descent, and as a speed retarding device, adapted for the same ent'forms, the same is herein claimed, without restriction to the specificform of the same described and shown.

In setting the auxiliary or timing weight 32, it may happen that the sleeve 81 exthat the time required for the descent of the timing weight 32 before the rack teeth 83 pinion 37, will be longer than the basket 26 said sleeve 31 extends above the pinion 37 vthe proper distance, pressure is applied to the push rod 44 and the yoke 42 of the guide member 41 moved out of contact with said sleeve, thus releasing the rack teeth 33 fromengag'ement withthe pinion 37 and the sleeve 31 may be moved downward the desired distance required to reset the timing weight. After the timing Wei ht 32 has said sleeve 31 is forced into engagement with said pinion 37 as is apparent Inasmuch as a device embracing the general features ".of construction hereinbefore set forth may bevariously modified in practice with respect to the form and arrangement of itsparts, I do notv desire to be limited to the specific features of construction except sofar as the same may be pointed out in the appended claims as constituting parts of my invention.
